About the 369-HI-0-M-F-E-0

369-HI-0-M-F-E-0 is a motor management relay that is manufactured by GE Multilin. The control power is 50-300 VDC / 40-265 VAC. This relay provides protection and monitoring for 3 phase motors and their associated systems. Additional features for the relay include the Modbus/TCP protocol Ethernet interface, the Profibus-DP rear communication port, the Profibus-DPV1 rear communication port, the DeviceNet protocol interface, a user-definable baud rate (1200-19200), flash memory for firmware updates, a front RS232 communication port, a rear RS485 communication port, a rear fiber optic port, a user-definable RTD type, 4 user-definable analog outputs, and a Windows-based PC program for setting up and monitoring the relay.

There are a number of metered quantities on the motor management relay. These include the phase currents and current demand amps, the motor load x fLA, the unbalanced current percent, the ground current amps, the input switch status (open or closed), the relay output status (energized or deenergized), the RTD temperature, the backspin frequency Hz, the phase and line voltages, the frequency Hz, the power factor lead/lag, the real power and real power demand watts, the reactive power and reactive power demand vars, the apparent power and apparent power demand VA, the real power consumption Mwh, and the reactive power consumption/generation ± Mvarh. The 369 MMR can ‘learn’ individual motor parameters and adapt itself to individual applications. In order to improve the protective capabilities of the relay, the user may adjust the motor inrush current, the cooling rates, and/or the acceleration time.
